Often people say non-electronic Nerf blasters aren't good for facing multiple people. which is true. So when you're left with a blaster that requires priming for each shot, you'll need to be prepared.

Steps

1

Make sure you have the right blaster. If you plan on using a springer against several people, at least makes sure you have one that that can do so.

Try to use a clip (magazine)-fed blaster, as they're faster to reload and there isn't necessarily a limit to ammunition, as oppose to a revolver where you can only have as many darts as there are barrels in the cylinder.

You should also make sure you have at least a few spare mags as while you aren't using that much of an ammo hungry weapon, you'll still perhaps need to reload at times.

2

Choose a good defence position. You are likely facing at least three or four opponents with no one to aid you, so you will need good defence that will provide you with cover from all directions. This way if you're surrounded or out-flanked, you will have cover and be able to avoid taking taking hits immediately.

3

Be considerate of how you fire. If you're using a blaster with a slam fire function, it would probably be wiser to wait until there are fewer enemies around before you se the slam fire mechanism. This is not because it wastes too much ammo but because you often need to be in a position that's more exposing and therefore more likely to be hit. So while you have more targets to hit, it's better to play it safe.

4

Try not to be the one firing all the rounds. Let your enemies go for the offensive. Try to draw one or two of them in closer and quickly fire at them when they close.
